Floribunda rose plant variety named `Intertyn`

ABSTRACT

A new variety of floribunda rose plant producing salmon colored flowers.

SUMMARY OF THE INVENTION

The present invention relates to a new and distinct variety of rose of the floribunda rose class which was originated by my crossing as seed and pollen parents two unnamed, unpatented, undistributed, proprietary seedlings of my creation. The varietal denomination of this new rose is `Intertyn`.

Among the novel characteristics possessed by this new variety which distinguishes it from its parents are its ability to produce commercially desirable sprays of attractive salmon colored flowers for the cut flower market.

Asexual reproduction by budding and grafting of the new variety as performed in Watsonville, Calif., shows that the foregoing and other distingishing characteristics come true to form and are established and transmitted through succeeding propagations.

BRIEF DESCRIPTION OF ILLUSTRATION

The accompanying illustration shows typical specimens of the flowers and vegetative growth of the new variety depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character. Phenotypic expression, including colors, may vary depending upon growing conditions, such as climate, soil, and environmental conditions.

DESCRIPTION OF THE NEW VARIETY

The following is a detailed description of my new variety, with color terminology in accordance with The Royal Horticultural Society Color Chart (R.H.S.C.C.).
